Question

solve the system by substitution.

$y = -9x$

$y = 2x + 33$

Explanation:

Step1: Substitute $y=-9x$ into second equation

$-9x = 2x + 33$

Step2: Isolate $x$ terms

$-9x - 2x = 33$
$-11x = 33$

Step3: Solve for $x$

$x = \frac{33}{-11} = -3$

Step4: Substitute $x=-3$ into $y=-9x$

$y = -9\times(-3) = 27$

Answer:

$x=-3$, $y=27$
